Perspective view of color-coded bathymetry of upper reaches of Horizon channel-levee complex. The main channel is ~3.5 km wide at its base and is incised ~120 m into the margin sediments. The large levee associated with Horizon Channel merges with the fan sediments of the Kruzofi fan complex. A huge meandering channel has cut >70 m into the levee sediments with a channel with of >4 km. The meanders have cut laterally >22 km. Distance from foreground to Chatham fan 192 km. Background behind margin is NOAA Chart 16016 draped over ETOPO2 DTM. Vertical exaggeration 15x, looking E.

Perspective view of color-coded bathymetry of almost-completely-buried seamount with associated moat (darker blue) and sediment mound (lighter blue). The seamount stands 240 m above the seafloor. It is surrounded by a sediment mound that is ~80 shallower SE of the seamount than on the NW. The entire feature is surrounded by a roughly circular moat (dashed line) 30 km in diameter. The moat is 50 m deeper and ~4 dB lower acoustic backscatter that the surrounding seafloor. The bedforms have wavelengths of ~2 km and wave heights of ~5 m. Vertical exaggeration 15x, looking E.

Perspective view of cascade-like landscape developed on the 5° margin. Each step of the major cascade (foreground) is a 100 to 200 m drop and the base of each step is a depression 20 to 40 m deep. Incipient cascades appears to be developing on the margin to the north (upper left in figure). 2000 and 3000-m isobaths are shown in black. Vertical exaggeration 15x, looking NE.

Perspective view of color-coded bathymetry showing the Transition Fault along the base of the margin with a 250 m deep, 500 m wide plunge pool at the end of a canyon. Vertical exaggeration 20x, looking N.

Perspective view of color-coded bathymetry of upper reaches of Surveyor Channel and major tributary. Both the canyon and its tributary are incised 120 m into the margin sediments. Notice subtle differences between bedforms and artifacts. Seamount and moat are shown in another perspective view. Vertical exaggeration 15x, looking SE.
